The systolic blood pressure (SBP) change after renal denervation did not differ by race in SYMPLICITY HTN-3.
The change in sham office SBP was, however, nearly twice as large in African Americans (AA) than non-AA.
The ambulatory SBP response among sham subjects and the larger office sham SBP response in AA may represent increased post-randomization medication adherence.
In multivariate analyses, sham SBP response appeared to be much larger in AA than non-AA prescribed a complex antihypertensive regimen.
